So that's 14 fatalities off the ship, 51 aboard ship, and 3 unspecified. Of the off-ship fatalities, only four were known to be security guards, with only one definite security death on an away mission, the far-from-anonymous Tasha Yar, prior to the 6th-season finale. Of the on-ship fatalities, only three were known to be security; but all in all, it looks like for the most part, you had considerably better odds of survival on an away team, not worse. (Although perhaps that's because TNG away teams usually consisted solely of regular characters.)

If anything, it seems that the most dangerous single posting on the ship was the conn, since at least three people died at that station -- plus there's the conn officer Q froze half to death in the pilot, and the conn officer who got sucked out into space in Nemesis, so the whole series is bracketed by conn officers suffering.
